Before I start: I’m programming for Iphone, using objective C.

I have already implemented a call to a web service function using NSURLRequest and NSURLConnection. The function then returns a XML with the info I need.

The code is as follows:

NSURL *url = [NSURL URLWithString:@"http://myWebService/function"];
NSMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url];
NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

i also implemented the methods

  • didRecieveResponse
  • didRecieveAuthenticationChallenge
  • didRecievedData
  • didFailWithError
  • connectionDidFinishLoading.

And it works perfectly.

Now I need to send 2 parameters to the function: “location” and “module”.
I tried using the following modification: 

NSMutableURLRequest theRequest   = [[NSMutableURLRequest alloc] initWithURL:url];
[theRequest setValue:@"USA" forHTTPHeaderField:@"location"];
[theRequest setValue:@"DEVELOPMENT" forHTTPHeaderField:@"module"];
NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

But it doesn’t seem to work.
I’m doing something wrong? is there a way to know if I’m using the wrong names for the parameters (as maybe it is “Location” or “LOCATION” or it doesn’t matter?)?
or a way to know which parameters is the function waiting for…

Extra info:
I don’t have access to the source of the web service so I can’t modify it.
But I can access the WSDL. The person who made the function say is all there… but I can’t make any sense of it >.<…

Any help would be appreciated. 🙂

    some examples about GET Post SOAP

    Soap Request

    POST /InStock HTTP/1.1

<?xml version="1.0"?>
<soap:Envelope

soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

<soap:Body xmlns:m="http://www.example.org/stock">
